Bain Capital-backed US LBM, a distributor of specialty building materials, completed the acquisition of American Construction Source, a national building materials distribution platform, from Angeles Equity Partners and Clearlake Capital Group, two private equity firms. Financial terms were not disclosed. “This transaction represents the culmination of our LBM investment thesis, and we enjoyed working alongside Jim Drexinger and his leadership team for the second time in this sector. The growth and transformation of the ACS platform represent an excellent example of our firm’s value creation model, leveraging both our operational and M&A capabilities. We have significant prior experience investing in this sector and were able to draw upon our best practices and relationships to drive a rapid transformation,” Timothy Meyer and Jordan Katz, Angeles Co-Founders and Managing Partners.
